Recent Advances of Mesoporous Silica Based Multifunctional Nano Drug Delivery Systems

Abstract

Mesoporous silica materials have attracted much attention for their potential biomedical applications due to their tailored mesoporous structure, large surface area, good biocompatibility, and the ease of surface functionalization. In the past few years, the mesoporous silica based drug nanocarriers have become the research focus of many researchers. This article reviews the recent research advances of mesoporous silica based multifunctional drug delivery systems with targeting modification and bioimaging, and details the design, surface modification, and applications in drug delivery field of mesoporous silica based drug delivery systems with diverse morphologies(such as hollow/rattle-type, nanotubes, etc.). Finally, we analyze the existing problems in practical applications and outlook the future development trends of mesoporous silica based drug delivery systems(including the specific morphological, multifunctional hybrid, and biodegradable mesoporous silica drug delivery systems).
